Abstract

Hooded rats were given extensive training on a VI 60" schedule until their response rate stabilized. Subsequently a punishment routine was initiated concurrently with the VI 60" for nineteen one hour sessions. While this routine was in effect, half of the Ss were administered a brief shock whenever they bar pressed; the other half served as tandem controls so the shocks which they received were not correlated with bar pressing. Two levels of shock intensity were employed: .2 and .4 ma. Behavior was suppressed in both treatment groups though to a much greater extent in the contingent group. Variations in shock intensity produced no apparent differences. There was no evidence of recovery from the effects of punishment in the contingent group. In the non-contingent group, there was some adaptation to punishment although these Ss did not reach their pre-punishment level of responding during the nineteen punishment sessions.
